LG has announced the Optimus GK, smartphone for the Korean market, that packs in all the features of the LG Optimus G Pro but replaces the huge 5.5-inch screen with a 5-inch one.

Similar to the Optimus G Pro, the Optimus GK's screen is also a 1080p (1080x1920 pixels) one with a pixel density of 440ppi. It's powered by a 1.7GHz Qualcomm Snapdragon 600 processor, and has 2GB of RAM. The phone will sport a 13-megapixel rear camera and a 2-megapixel front-facing one. It will offer 16GB of internal storage expandable up to 64GB via microSD,and come with a 3,100 mAh battery. It will also come with LTE support.

It's interesting to note that LG had released the LG Optimus G Pro in Japan with a 5-inch screen. It might have to do with the reason that a large number of people find 5-inch+ phones difficult to handle.

It's not known if LG would extend the phone to other markets but if it does, then the Optimus GK would directly compete with the Samsung Galaxy S4 as both phones sport similar specifications.

The launch comes at a time when LG is all set to launch the LG Optimus G Pro in the US with carrier AT&T. It had also showcased the phone in India with an expected launch in June.

Rumours related to the existence of the LG Optimus G2, LG's next flagship phone have already started doing the rounds, with a listing on a benchmarks site pointing to the existence of the phone.
